In the Ro'Meave Family arc, Katelyn pretended to date Aphmau to further make their lie worse. However, Katelyn volunteered to kiss Aphmau without hesitation. While most of the guys think it's crazy, Travis replies that it's his OTP. This also hints that Katelyn might be Bisexual, but they claim each-other as sisters. In some Mini Games Aphmau and Katelyn have flirtatiously teased each other. Same as with Gaurance, the relationship seems to be no more than good friends.
